STRAW-BURNER.

PECEICATION forming part of Letters Patent No. 391,255, dated October 16, 1888.

Application filed December 27, 1887. Serial No. 259,066.

To all whom it may concern.-

Beit known that I, GODFRIED LAURE, a citizen of theUnited States, and aresident of Huron, in the county of Beadle and Territory of Dakota, have invented certain new and useful Improvements in Straw-Burners; and I dohereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the sanie,reference beinghad to theaccompanyingdrawings, which form a part of this specitleation,and in which- Figure 1 is a perspective view of my improved straw-burner. Fig. 2 isa perspective view ofthe frame, and Fig. 3 is a similar view of the cylinder.

My invention has relation to devices for burning straw for heating purposes; and it consists in the following improved construction and combination of parts.

Referring to the accompanying drawings, in which the same gures of reference indicate corresponding parts in cach of the figures, 1 indicates the frame, 2 the magazine, and 3 the cover or top. The frame is preferably made of rod-iron, and consists of the three long legs or supports et, a short leg, 5, a circular ring, G, and the cross pieces or braces 7. At their upper ends these three longer legs are bent or curved toward each other, as shown, and secured to a pipe, S. About midway between the top and bottom a semicircular brace or support, 9, is sccuredto which the shelves 10 are attached. This frame can be riveted or welded together, as may be desired, and is made of such size and strength as are sufficient to support the cylinder, and also to support the ordinary stovepipe,whieh is placed upon the upper end of the short pipe S, in the usual manner.

The straw is placed within the magazine or receptacle 2, which is preferably made cylindrical. Upon the bottom of this receptacle, on its inner side, is secured a draft-tube, 12, preferably formed of sheet metal, and about half-round in cross-section. Draft-holes 13 are formed in the upper portion of this tube, which, together with its open end and the 'notches 14 upon its lower edge, permit of suiiicient draft from the bottom for burning the straw. A hole, 15, is formed in one side of the cylinder,

(No model.)

at the bottom, over which one end ofthe tube 12 is placed, thus affording communication between the outer air and the interior of the tube. An inclined draft flue or cup, 16, is secured to the side of the cylinder, with its lower end inclosing the hole 15. The upper portion of this flue is iianged, as shown at 17, upon which is adjustably secured the damper 1S. A brace, 19, is secured at its ends to the side of the cylinder, and at its middle portion to the upper portion of the iiue 16, thus forming a handle upon each side of the flue, by means of which the cylinder can be turned up in emptying out the ashes, te. The cover of this cylinderZOis preferably madecone-shaped, and has a tube or pipe, 21, extending from its top up into the piece of pipe 8, by means of which communication is established between the interior of the cylinder and the stove-pipe. rThe rim 22 of this cover ts within the top of the cylinder or magazine and is provided with a series of holes, 23. Upon the portion of the tube 21 which projects up within the pipe 8 is a lug or pin, 24, which projects out through a slot, 25, in the side of the pipe S. This slot is of such a length that when the lug 24 is at its highest point the cylinder can be slipped out from under the cover; but when the lug is in the lowest portion of the slot the rim of the cover tits down tightly within the top of the cylinder. Upon one side of this slot are formed two notches or catches, 26 and 27, the upper one of which, 26, is used for holding the cover in its highest position, and the other one is placed near the lower end of the slot and is used for holding the cover in a partly-elevated position. The cover is provided with two handles, 2S, by means of which it can be moved up and down and partly rotated. An ordinary damper, 29, is placed in the pipe 8 above the upper end of the tube 21.

In use I prefer to have two cylinders, so that one can be filled while the other is burning, although one cylinder may be used, which can be removed and refilled. After a cylinder has been filled with straw it is placed within the frame and lighted at the top. If it is desired to have `the straw burn very slowly, the cover is retained inits elevated position,which permits of an abundant draft at the top of the cylinder and prevents the rapid consumption IOO of the straw. If, however, it is desired to have it burn rapidly, the cover is' fitted down tightly upon the cylinder and the damper at the bottom opened to its full Width,whieh will cause all of the draft to come in at the bottom of the cylinder and pass up through the burning straw. lf a medium fire is desired, the cover is raised, so that the lug 24 will engage with thenotch 27, which will raise the rim of the cover out of the top of the cylinder just enough to expose the series of holes 23,which Will permit of a partial draft at the top of the cylinder. Then, by means of the damper at the bottom of the cylinder and the damper within the pipe, the draft can be regulated atwill. After the straw within the rst cylinder has been consumed the cover is raised to its highest point and retained by causing the lug 24 to engage with the top notch, 26. The cylinder is then removed by means ofthe handles 30 upon its sides and a filled cylinder is put in its place and the tire started and controlled in that, as above described. Before filling the cylinder just emptied the ashes can be cleaned out of it by turning it upside down by means of the handles secured to it at the sides of the damper, near the bottom.

By means of the construction above described the cylinder is formed with but one hole, and that near the bottom, and the usual necessity of an ash-pan is dispensed with, and

thus all danger of spilling ashes over the room is entirely avoided. By means of the shelves at the sides of the cylinder different articles can be heated or kept Warm, such as tea, coffee, and the like.

The device is simple, yet it is strong, is neat and convenient, and in localities Wheret'here exists a scarcity of other fuel it will be found to be a great and valuable improvement.

Although I have shown and described the particular construction of the magazine and pipes, I make no claim for them in this application, as such construction is fully covered in application, Serial No. 259,040, filed December 27, 1887.

Having thus described my invention, I claim- In a straw-burner, the combination, with a cylinder and a cover therefor, of a frame con sisting of three long legs and one short leg, a ring nearvthe bottom of the long legs, crossbraces secured thereto, and a pipe secured to the tops of the long legs.

In testimony that I claim the foregoingas my own I have hereunto aflixed my signature in i presence of tWo Witnesses.
